Answer 2

Answer:

D. 48

Step-by-step explanation:

Let's first find the probability that in the first 40 trials, exactly two of the coins are heads.

We know that there were 16 such outcomes of 2 heads and 1 tail, and there was a total of 40 possible outcomes. So our probability is:

16 / 40 = 4 / 10 = 2/5

We can assume that the probability that in the next 120 trials, about 2/5 of the outcomes will also be 2 heads and 1 tail. So, we multiply 2/5 by 120 to figure out that exact number:

(2/5) * 120 = 240/5 = 48

The answer is thus D.
